Prize Calculator — Party Game Prizes
Estimate prizes needed for party games and competitions.
How We Calculate This
This calculator estimates total prize quantities and costs based on games and winners.
Formula
- Winner prizes = number of games × winners per game
- Participation prizes = number of children (one per child, when a participation prize cost is entered)
- Spare prizes = (winner prizes + participation prizes) × spare % (rounded up)
- Total prizes = winner prizes + participation prizes + spare prizes
- Grand total = (winner prizes × winner cost) + (participation prizes × participation cost) + (spare prizes × winner cost) + (total prizes × wrapping cost)
Spare prizes and wrapping cost are optional (in Advanced Options) and default to zero, so by default the grand total is simply the winner and participation prize costs.
Frequently Asked Questions
For 5 games with 3 winners each, you need 15 prizes. Add participation prizes if children are under 5 to avoid tears. A good rule is 2-3 prizes per game for winners and runners-up. For pass the parcel, every layer should have a small prize.
Stickers, small toys, bouncy balls, mini colouring books, bubbles, temporary tattoos, erasers, and small bags of sweets. Avoid expensive prizes that create jealousy. Keep all prizes roughly equal value. Pound shops are excellent for bulk party prizes.
For under-5s, yes - give participation prizes to everyone. For ages 5-7, have winners but give small consolation prizes. For 8+, children understand competition better and winners-only is fine. Always ensure no child goes home empty-handed by including prizes in party bags.
Budget £0.50-£2 per prize. Winner prizes can be £1-£2 and participation prizes £0.30-£0.50. For 15 children and 5 games, a typical prize budget is £15-£30. Buying in bulk from pound shops or online party suppliers gets the best value.
